USA. Colorado's legal cannabis farms emit more carbon than its coal mines
Legal cannabis production in Colorado alone emits more greenhouse gases than does the state’s coal-mining industry. The energy required to yield one kilogram of dried flower from cannabis grown indoors generates the equivalent of 2–5 tonnes of CO2, depending on where the plant is grown. Most US cannabis is grown indoors under artificial lights, either for legal reasons or to avoid theft. “The profit margins are so huge that you don’t have to be making super energy-conscious decisions,” says Jason Quinn, who analysed the carbon footprint of the emerging US cannabis industry.
